Only when is cold out my serpintine belt starts squeeling and gets quiet when i'm to speed. Anyone know why?

Most likely it either needs to be tightened or replaced. If it was a bad bearing in the alt, water pump, idler, etc. the squeeling would probably be constant or come and go as the engine rpm changed.

Ok. I'll have to check it out. Thanks

I forgot to mention, take a look at the ribbed side of the belt. If it's hard and cracked replace it.

Also if there is not a sticker with the belt diagram on it under the hood, make a sketch of if first. I didn't one time, and it's amazing how long it can take to figure out how it's supposed to go on.

Yeah i have the sticker. I've already replaced it once.

Find where the belt has a fairly long straight section. Engine off - give it a twist - if you can twist it 90 degrees it's too loose. Should only twist about 45 degrees.

I'll try that. Thanks

also id throw some dressing on it helps to keep it from squealing and cracking
